Abstract
The present invention is directed to an entity comprising a particle attached to at least one polymer M through one or several supramolecular interactions -A-B- constituted by 2 to 8 hydrogen bonds X-H-Y, wherein A and B are functional groups respectively grafted to P and M thus forming the particle-containing entity P-(A-B-M)x with x being greater than or equal to 1, functional group(s) B being positioned at one end of the polymeric chain of polymer M, X and Y are heteroatoms present in A and B functional groups, H is hydrogen, and M has a degree of polymerization comprised between 5 and 1000, preferably ranging from 5 to 500. The invention is also directed to a method for preparing this particle-containing entity P-(A-B-M), a method for sequentially forming and breaking the supramolecular interactions -A-B- in said particle-containing entity P-(A-B-M)and dispersions comprising the same.
